Defined TI zone configuration:
TI Zone Name: TI_Zone_ALL
Port List: 20,3; 20,4; 20,5; 20,6; 30,7; 30,8; 30,9; 30,10
Configured Status: Activated / Failover-Enabled
Enabled Status: Activated / Failover-Enabled
Then enabled status now displays as "Activated".
General rules for TI zones
The following general rules apply to TI zones:
• A TI zone must include E_Ports and N_Ports that form a complete, end-to-end route from initiator to
target.
• When an E_Port is a member of a TI zone that E_Port cannot have its indexed swapped with
another port.
• A given E_Port used in a TI zone should not be a member of more than one TI zone.
If multiple E_Ports are configured that are on the lowest cost route to a domain, the various source
ports for that zone are load-balanced across the specified E_Ports.
• TI zones reside only in the defined configuration and not in the effective configuration. When you
make any changes to TI zones, including creating or modifying them, you must enable the effective
configuration for the changes to take effect, even if the effective configuration is unchanged.
• A TI zone only provides traffic isolation and is not a “regular” zone.
• Routing rules imposed by TI zones with failover disabled override regular zone definitions. Regular
zone definitions should match TI zone definitions.
• FSPF supports a maximum of 16 paths to a given domain. This includes paths in a TI zone.
• Each TI zone is interpreted by each switch and each switch considers only the routing required for
its local ports. No consideration is given to the overall topology and to whether the TI zones
accurately provide dedicated paths through the whole fabric.
For example, in the following figure the TI zone was configured incorrectly and E_Port "3,9" was
erroneously omitted from the zone. The domain 3 switch assumes that traffic coming from E_Port 9 is
not part of the TI zone and so that traffic is routed to E_Port 11 instead of E_Port 12, if failover is
enabled. If failover is disabled, the route is broken and traffic stops.
